Chris Daigle, Product Manager
Voice AI isn't 100%, but Vapi is easy to use and definitely some of the best voice AI capabilities I've seen...

Note: There are no reviews for Vapi on G2, Capterra, or Trustpilot at this time. Users should be cautious and consider this when evaluating broader sentiment.

PolyAI

"Exceptional capability"
Anonymous Reviewer (G2)
I loved PolyAi for its exceptional capability to automate client calls. Their customer support is commendable. The interface is simple and very user friendly...

"Competitor offerings seem robotic"
Anonymous Reviewer (G2)
The assistant itself is lifelike and constantly learning... In comparison, competitor offerings seem robotic make customers feel like they are not being cared for...

Note: While there’s no single average rating number provided by G2 or other platforms in public summaries, all available written feedback points toward a strong reputation among enterprise users.

What users are saying about Ringly.io:

Ringly.io is known for its simplicity, and a focus on e-commerce, with features like order status lookups, returns and product questions. It has a 4.8 star rating from 12 reviews on Product Hunt and other platforms.

However, I must express that the product has shown significant promise. When compared to competitors, it stands out significantly ahead.

"It really sounds like a human" - Laix, Founder. Tried Ringly.io today and the quality of the phone calls surprises me! It really sounds like a human, and it reacts really fast. Will need to deploy it in action to see the full capabilities.

Why Ringly.io is a Better Choice

‍

‍Best for Shopify stores looking for the best way to offer 24/7 AI phone support at a fraction of the cost.

How it went when I tried setting up Ringly:

After I installed the Shopify app, the only thing I had to do was to upload my data to the knowledge base. (website was uploaded automatically)

After I did that, I could already speak to my agent via a web call.

Setting it live was as simple as picking a phone number with my area code from the dashboard. I was able to connect the number with 1 click. (The number is also free and included)

There was not really anything else to the setup.

They claim that Seth, their AI phone agent, resolves up to 90% of support calls. They back that up with 200,000+ calls handled.

Signup -> onboarded took under 1 hour. Most of that time was spent waiting for the knowledge to be uploaded.

Over the first 2 weeks I used it, it resolved 76% of my calls on its own.

The rest of the calls were escalated to a support ticket by my agent.

(update: the more calls you get, the smarter it gets. As of today, my resolution rate is 79%.)

Standout Features (pros):

Very easy setup (almost none)
65% resolution guarantee

Pricing is $99/mo for the first 50 calls, then $1.99 per call. If Seth resolves under 65% of calls in a month, that month comes back as credit (after 90 days on Pay per call).

Shopify integration is native. It will allow your agent to solve order status and refund requests on the phone.

Reviews are overall very positive, mainly because of the 65% resolution guarantee.

Cons:

Phone support only

What’s unique about Ringly is that it is the first AI phone support tool built for Shopify.
